covers the first 30km its journey in 45 min
and covers the remaining 25 km in 35 min. what is avarage
speed of car?
​

Answer 1

Answer:

11/16 km

Step-by-step explanation:

distance covered in 45 min = 30 km

distance covered in 35 min = 25 km

total distance covered = 30+25 = 55 km

total time taken to cover the 55 km = 45+35 = 80 min

Average Speed = Total distance / Total time

= 55/80 km

= 11/16 km

Formula: AS = TD/TT
